Summary: Malicious code in @sudoughnym/enviro-demo (npm)

Details: Source: amazon-inspector (02c1c204d0f458d13d7140f4b7a007d551095665a418e9146037be9a5b2b7957) @sudoughnym/[email protected] ships preinstall.js and postinstall.js lifecycle scripts that run automatically on `npm install`. Both scripts collect host identifiers and environment metadata — os.hostname(), process.cwd(), pid, node version, platform, process.env.USER, the first ten environment variable names, and the total env count — and POST them as JSON to https://webhook.site/f83b073c-a04a-4ac5-8930-507051bd22f7, a third-party webhook capture service not associated with the package's stated publisher. The package version (99.99.99) and its own description identify it as a dependency-confusion proof-of-concept targeting an internal `enviro` package name; the inflated semver is intended to outrank private-registry versions so internal build systems resolve to this public package. Installer harm: any build or developer machine that resolves to this version leaks host identity and environment-variable layout (which can include secret-bearing variable names) to an attacker-controlled endpoint on every install.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
